c-ares: remove custom patches

Current patch is breaking the library dependencies added by cmake
especially when you are static linking.

Applications need the ws2_32 library to be linked for mingw32
and with the existing patch this is not getting passed to the users.

Current patch seems to address this issue:
https://github.com/c-ares/c-ares/issues/373

Both issues are resolved in 1.17.2:

1.17.2-r0/git $ find . | grep c-ares-config.cmake.in
./c-ares-config.cmake.in
1.17.2-r0/git $ find . | grep libcares.pc.cmake
./libcares.pc.cmake
